CHS 219x10 GOST · Weight & Dimensions

GOST, cold-formed sections · Circular Hollow Section

Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.

Also known as: Caño estructural redondo (Argentina)

The CHS 219x10 steel profile weighs 51.5 kg/m (34.63 lb/ft). Cross-sectional area: 6,565.929 mm². Moment of inertia Ix = 3,593.287 cm⁴, Iy = 3,593.287 cm⁴.
